AI Technical Summary

Problems solved by technology

[0014] However, the LiDAR sensor is an expensive sensor
Also, since this LiDAR sensor has only been developed recently, it is still difficult to know how to utilize wind field characteristics such as wind speed, wind direction, wind shear, turbulence, induction factors, etc. by converting the raw data from the LiDAR sensor
Therefore, such LiDAR sensors require complex implementations to determine the wind speed in the rotor plane

Embodiment Construction

[0055] The invention relates to a method for determining the wind speed in the rotor plane of a wind generator in real time.

[0056] As a non-limiting example, figure 1 A horizontal axis wind turbine 1 according to an embodiment of the present invention is schematically shown. Generally, the wind generator 1 is capable of converting the kinetic energy of the wind into electrical or mechanical energy. For wind energy conversion, it consists of the following facilities:

[0057] - The tower 4, which positions the rotor (not shown) at a sufficient height to enable it to move (necessary for horizontal axis wind turbines), or to position the rotor so that it can be moved by At altitudes where stronger and more frequent wind drives are present. Tower 4 generally houses electrical and electronic components (modulators, controllers, multipliers, generators, etc.),

[0058] - The nacelle 3, mounted at the top of the tower 4, houses the mechanical, pneumatic and some electrical and...

Abstract

The invention relates to a method for determining the wind speed in the plane (PR) of the rotor of a wind turbine (1) by measuring the rotational speed of the rotor, the angle of the blades and the generated power. A dynamic wind turbine model, a dynamic wind model and an unscented Kalman filter are implemented according to the method of the invention.

Description

technical field [0001] The present invention relates to the field of renewable energies, and more particularly to wind generators, measurement of wind resources, with wind forecasting, turbine control (orientation, torque and speed regulation) and / or diagnostic and / or monitoring objectives. [0002] Wind turbines enable kinetic energy from the wind to be converted into electrical or mechanical energy. For wind energy conversion, it consists of the following facilities: [0003] - A tower that positions the rotor at a sufficient height to enable it to move (required for horizontal axis wind turbines), or such that it can be driven by stronger and more frequent winds than at ground level height. Towers usually house electrical and electronic components (modulators, controllers, multipliers, generators, etc.), [0004] - The nacelle, mounted at the top of the tower, houses the mechanical, aerodynamic and some electrical and electronic components required to run the turbine. t...
